European Measuring Instruments Directive (MID):
The MID 2004/22/EG was updated by the revised version 2014/32/EU at the 20.04.2016 and supplemented by 2015/13/EU. The law stipulates, how measuring devices have to be manufactured and conformity assessed (conformity assessment replaces the first calibration) as well as its placing on the market (transition between manufacturer and user).
The International Organization of Legal Metrology is an intergovernmental treaty organization, which is specialized in the global harmonization of legal metrology procedures in order to facilitate international trades. The organization makes recommendations, which are recognized within many countries and influence national norms.
OIML R:129 is a recommendation, which specifies the metrological and technical requirements for the pattern approval of multidimensional measuring instruments. These instruments are used to determine the dimensions and/or volume of an object for the purpose of calculating charges for postage, freight or storage. The recommendations are recognized globally.
Dimension weight, also called volumetric weight, is a practical value in order to evaluate the costs of a consignment in air cargo (partially also in other fields). Logistic suppliers, airlines and shipping companies as well as parcel services determine the dimension weight for each transport in order to charge light but rather big, voluminous consignments appropriately at a higher price. Example: 1m3= 166 kg taxable weight (air cargo). MID approved equipment empowers you to invoice on Actual Weight or Dimension Weight, which ever is highest.
